AR means after rebate. For instance, the hard drives actually cost me $80, but there's an online rebate for $50, so in 4-8 weeks, I'll get a check for the difference.

Lots of times, rebates fall through the cracks, and people just forget about them. Staples is really good about theirs tho, and since it's online, it's easy tracking. The only rebate I had to do was at Radio Shack (for the keyboard/mouse), and it's only $20.

What is it they say about silence being golden?
